中文摘要：

土壤风蚀是包括风、植被、土壤特性、土地利用方式、降水、微地形等多要素交互作用，发生在特定地理空间，具有独特的气流一土壤界面相互作用机制的连续动力学过程。基于统计学理论的土壤风蚀经验模型，不仅难以避免子模型之间有多个风蚀影响要素的交叉出现，使子模型之间不能严格地相互独立，导致建模理论基础存在不足，而且不能客观反映土壤风蚀的动力学过程。在厘清土壤风蚀基本概念，分析国际土壤风蚀影响因子和土壤风蚀模型研究历史与存在不足的基础上，提出一个新的基于风蚀动力学理论的土壤风蚀模型理论框架，以及在此模型框架下土壤风蚀影响因子的分类与表达。阐述了该模型框架和影响因子分类与表达的合理性，并对土壤风蚀影响因子分类与表达的研究途径进行了探讨。

英文摘要：

Soil erosion is an interaction of multi factors including wind, vegetation, soil characteristics, land use, precipitation, micro-geomorphology and so on. It is a continuous dynamic process occurring on airflow-soil in- terface in the specific geographical locations. Soil erosion empirical model, based on statistic theory, is difficult to avoid overlap of some factors affecting soil wind erosion between sub-models and not enable sub-models to be strictly independent from each other, thereby leading to lack of theoretical basis for modeling. Such empirical model is also not able to objectively reflect dynamic process of soil erosion. On the basis of clarifying basic concepts of soil ero- sion and analyzing the global research background and inadequacy, we proposed a new theoretical framework for soil erosion models based on wind erosion dynamics theory and the classification as well as representation of factors affecting soil wind erosion under the framework. We also elaborated the rationality of both the framework and the classification as well as the representation of factors affecting soil wind erosion, and further explored the research approaches on the latter.
